Insert to Modify Powertec 70396 Blast Gate

This insert fixes the excessively loose fit of the Powertech 70396 steel gate within the blast gate shell. This insert may be printed in PLA, PETG, nylon, ABS, etc., and is glued onto the inflow side of the gate, eliminating all but about 5-8 thousandths of an inch of the excess clearance in the gate channel. The insert does not interfere with gate function and eliminates much of the leakage seen during use. I recommend using medium CA to glue the insert in place.
